Power factor correction AC-DC boost converter using PI-hysteresis current control

Modified Bi-directional AC/DC Power Converter with Power Factor Correction

Most existing power  converters and industrial motor drive systems draw non-sinusoidal currents from the supply. Non-sinusoidal currents contained harm harmonics disturb the power supply which it causes serious concern for reliability. Other equipments that use the same power supply are adversely affected. This paper suggests the operation and performance of a new modified AC/DC converter that ...

The Analysis of Ac-dc Boost Pfc Converter Based on Peak and Hysteresis Current Control Techniques

This paper presents two current control techniques of an ac-dc boost converter to obtain unity power factor (PF). Single phase high power factor rectification is the most frequently accomplished using a boost converter. This converter reshapes distorted input current waveform to approximate a sinusoidal current that is in phase with the input voltage. There are several current control technique...

Generalized Average-current-mode Control of Single-phase Ac-dc Boost Converters with Power Factor Correction

The dissertation presents a generalized average-current-mode control technique (GACMC), which is an extension of the average-current-mode control (ACMC) for single-phase ac-dc boost converters with power factor correction (PFC). Traditional ACMC is generalized in a sense that it offers improved performance in the form of significant reduction of the current control loop bandwidth requirement fo...

Boost Converter for Power Factor Correction of DC Motor Drive

With the increasing demand for power from the ac line and more stringent limits for power quality, power factor correction has gained great attention in recent years. A variety of circuit topologies and control methods have been developed for the PFC application. While the discontinuous conduction mode (DCM) converters such as boost and flyback converters are well suited for low power applicati...
